WBPhenotype:0000385
|
sperm excess
|
Animals produce an increased sperm population compared to control. |
|
WBPhenotype:0001683
|
spermatogenesis defective hermaphrodite
|
Variations that specifically disrupt sperm production in XX hermaphrodites. By contrast, spermatogenesis in XO males remains unaffected. |
|
WBPhenotype:0001097
|
premature spermatocyte germ cell differentiation
|
Unspecialized male germ cells (spermatocytes) prematurely acquire the specialized properties of functional sperm. |
|
WBPhenotype:0000390
|
spermatid activation defective
|
Spermatids fail to mature into active sperm. In C. elegans round sessile spermatids mature into spermatozoa (polarized cells with a motile pseudopod), upon copulation or treatment with proteases. |
|
WBPhenotype:0000981
|
spermatocyte meiosis variant
|
Animals exhibit variations in the meiotic divisions undergone by the primary and secondary spermatocytes to produce haploid spermatids (non-motile sperm) compared to control. |
|
WBPhenotype:0000982
|
spermatid maturation variant
|
Animals exhibit variations in the ability of a relatively unspecialized spermatocyte to acquire the properties of a spermatid cell compared to control. |
|
WBPhenotype:0001829
|
premature spermatid activation
|
Any variation that results in the premature differentiation of spermatids into motile spermatozoa compared to control. |
|
WBPhenotype:0000356
|
spermatogenesis delayed
|
The progression of immature germ cells to functional sperm is retarded compared to control. |
